Elliot Rodger, 22, went on a violent shooting spree on May 24, killing six people and injuring 13 around the Santa Barbara campus before killing himself.

Shortly before the attack, Rodger had written an angry statement and posted YouTube videos in which he blamed the planned shooting spree on his hatred for women, whom he said had snubbed him.

Among those killed was 20-year-old Christopher Martinez.

In the newly released photos, Martinez's father, Richard Martinez, and Peter Rodger, father of the gunman, are shown talking and embracing. They meeting took place June 1 in Santa Barbara.

"We plan to work together so other families such as ours will not suffer as ours have," Martinez told ABC News affiliate KEYT-TV. "This was a private conversation between grieving fathers who've reached common ground."
